Kua tāruatia ki te papatopenga
5x+10y-\left(3x+13y\right)=14
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2y.
5x+10y-3x-13y=14
Hei kimi i te tauaro o 3x+13y, kimihia te tauaro o ia taurangi.
2x+10y-13y=14
Pahekotia te 5x me -3x, ka 2x.
2x-3y=14
Pahekotia te 10y me -13y, ka -3y.
2x=14+3y
Me tāpiri te 3y ki ngā taha e rua.
2x=3y+14
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{3y+14}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3y+14}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{3y}{2}+7
Whakawehe 14+3y ki te 2.
5x+10y-\left(3x+13y\right)=14
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2y.
5x+10y-3x-13y=14
Hei kimi i te tauaro o 3x+13y, kimihia te tauaro o ia taurangi.
2x+10y-13y=14
Pahekotia te 5x me -3x, ka 2x.
2x-3y=14
Pahekotia te 10y me -13y, ka -3y.
-3y=14-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{14-2x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{14-2x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{2x-14}{3}
Whakawehe 14-2x ki te -3.
